I agree, not an all the time thing, but when it does happen ( I have to be in the mood), it is pretty good.

I have found that using a vibrator w/clit tickler at the same time really ads to the feeling at first. Generally I have a masive climax. After that, I usually take the vibe out because by then I am very very sensitive. I can climax, but it isn't as intense as when using a vibe/clit tickler.

Word of advise..........use a whole lotta lube and start out slow. A small butt plug (maybe one that vibrates) will help to start with and streach and relax the rectum! Nothing is worse than having to stop because you are drying up. The rectum doesn't produce natural lubrication like the vagina does. My husband has the bottle very near and will douse his cock as he is going in and out a few times. Hope this helps. Also, have him use a condom, that way the lube will stay a little longer.

You will probably like it once you get used to it.
